fixup! Add test case for ima file signatures

We need double [[ and ]] because one level is consumed by M4 and that
causes the resulting query format to only print one file, not all.

That also means we can no longer just cut the first 20 chars, replace
the signature hex string with a (...), we only care about there being a
signature on every file.
